Objectives: This study compared the characteristics of the work environment between agricultural and general workers and analyzed the effects of agricultural working characteristics on work-related health problems. Methods: The participants of this study were 2,347 agricultural workers and 48,042 general workers who were selected by applying standardized weights to the raw data of 50,538 respondents from the 6th Korean Working Condition Survey (KWCS). Variables applicable to both worker groups and related to exposure to hazardous risk factors in the working environment, working hours and intensity of work, health problems and work-related status, and satisfaction with the work environment were selected. Chi-square tests and independent sample t-tests were performed to evaluate the differences in the variables between the two groups. Multivariate logistic regression analysis was conducted to analyze the effects of work environment characteristics on work-related health problems. Results: Compared to general workers, agricultural workers were more exposed to hazardous environments, irregular work patterns such as working on Saturday/Sunday, and short repetitive tasks. They reported more work-related and general health problems, including back pain, upper extremity muscle pain, lower extremity muscle pain, and general fatigue. Agricultural workers showed lower satisfaction with their work environment than general workers. Factors affecting one or more work-related health problems included gender, working years, hazardous factors, irregular work pattern, working hours, and labor intensity. Conclusions: Our findings showed that agricultural workers were relatively more vulnerable to safety issues compared to other occupational groups. Therefore, it is necessary to establish standardized safety and health standards and strengthen systematic safety and health management policies and services for agriculture.

Purpose: This study aimed to identify the levels of oxaliplatin-induced peripheral neuropathy (OXLIPN) and the quality of life (QOL) related to OXLIPN in patients with digestive system cancer. Methods: A total of 83 patients with chemotherapy-induced peripheral neuropathy (CIPN)-related symptoms participated in this study. Data were collected through self-reported questionnaire which were constructed to include general and clinical characteristics, EORTC QLQ-C30, Patient Neurotoxicity Questionnaire (PNQ), and EORTC QLQ-CIPN20. Results: The average scores of OXLIPN upper and lower extremity scale were 30.01 and 29.16, respectively. The average scores of PNQ sensory and motor scale were 2.11 and 1.70, respectively. The mean score of the QLQ-C30 global health status was 54.85, and the range of mean score of the functional and symptom subdomains was 34.85~73.29 and 17.67~53.54, respectively. The CIPN-related symptoms positively correlated with the global health status scale and all subdomains of functional scale, respectively and negatively correlated with fatigue, pain, dyspnea, insomnia, and financial problem subdomains of the symptom scale, respectively. Conclusion: Oncology nurses should pay attention and provide remedies for CIPN symptoms reported by their patients. Nursing interventions should be developed for patients with digestive system cancer to alleviate CIPN and enhance their QOL.

Mesenchymal chondrosarcoma is a rare tumor occurring in both bone and soft tissues and exhibits characteristic of a malignant nature. The authors experienced a case of mesenchymal chondrosarcoma occurring in a 23-year-old woman which had invaded the cervical spine. The patient presented with severe both shoulder pain, left upper extremity weakness(Grade IV) and paresthesia at admission. Radiologic studies of the cervial spine showed an aggressive osteolysis of C4 vertebral body, pedicle and lamina with compression of the spinal cord posteriorly on C3, C4, C5 levels. The tumor was totally removed by a combined anterior and posterior approach. The removed vertebral body was replaced with autogenous bone and stabilized by Codman locking plate symtem. The pathological examination showed characteristic of mesenchymal chondrosarcoma.previous symptoms well improved postoperatively. The authors present a case of mesenchymal chondrosarcoma with review of literature.

Sarcoidosis is a systemic disease of unknown etiology that may affect any organ in the body. The nervous system is involved in 5-16% of cases of sarcoidosis. Here, we report a case of intramedullary sarcoidosis presenting with delayed spinal cord swelling after laminoplasty for the treatment of compressive cervical myelopathy. A 56-year-old woman was admitted to our hospital complaining of upper extremity pain and gait disturbance. The patient had undergone laminoplasty for compressive cervical myelopathy 3 months previously. Follow-up magnetic resonance imaging revealed a large solitary intramedullary lesion with associated extensive cord swelling, signal changes, and heterogeneous enhancement of spinal cord from C2 to C7. Spinal cord biopsy revealed non-necrotizing granulomas with signs of chronic inflammation. The final diagnosis of sarcoidosis was based upon laboratory data, imaging findings, histological findings, and the exclusion of other diagnoses. Awareness of such presentations and a high degree of suspicion of sarcoidosis may help arrive at the correct diagnosis.

For many stroke patients undergoing rehabilitation therapy, there is a need for indicator for evaluating the body function in paretic and non-paretic regions of stroke patients quantitatively. In this paper, the function of muscles and cells in paretic and non-paretic regions of severe and mild hemiplegic stroke patients was evaluated using multi-channel bioelectrical impedance spectroscopy. The paretic and non-paretic regions of severe and mild stroke patients were quantitatively assessed by using bioelectrical impedance parameters such as prediction marker (PM), phase angle (${\theta}$), characteristic frequency ($f_c$), and bioelectrical impedance vector analysis (BIVA). The mean values of impedance vector were significantly discriminated in all comparisons (severe-paretic, severe-non-paretic, mild-paretic, and mild-non-paretic). The bioelectrical impedance parameters were proved to be a very valuable tool for quantitatively evaluating the paretic and non-paretic regions of hemiplegic stroke patients.

PURPOSE: This study aimed to examine the pain, range of motion (ROM), upper extremity task performance, and functional levels of patients after rotator cuff repair according to the timing of a closed chain exercise thereby presenting basic data for an effective rehabilitation program. METHODS: The intervention was applied three times per week, one hour per day, for four weeks to 40 participants, 78 of whom had undergone rotator cuff repair. The participants were divided into four groups and assigned to usual general physical therapy and an open chain exercise. Group I consisted of the open chain exercise only. The closed chain exercise was applied to group II after the 4 times, group III after the 7 times, group IV after the 10 times. Measurement were used ROM, visual analogue scale (VAS), box and block test (BBT), and shoulder pain and disability index (SPADI). A one-way analysis of variance was conducted to test differences. RESULTS: There were significant differences in the internal/external rotation between group I and group II. The VAS significantly differed between group II and group I, group III, and group IV. The BBT results of group II and group I were significantly different compared to those of group IV. The SPADI significantly differed between group II and group I and between group II and group IV. CONCLUSION: The closed chain exercise was effective for patients following rotator cuff repair from the second week after active exercise was prescribed, verifying its applicability in rehabilitation programs.

Prolotherapy can be defined as the injection of growth factors or growth factor production stimulants to grow normal cells or tissue. Even though it has been a controversal procedure for decades, it is currently gaining in popularity among many physicians. The term prolotherapy was coined by Hacket in the 1950s to imply proliferation of normal tissue at ligamentous and tendinous entheses. The procedure has been described by other terms, such as sclerotherapy, regenerative injection therapy, and stimulated ligament repair. Incomplete healing from sprains or strains is common and can lead to chronic pain, joint instability and laxity, and is a risk factor for the development of osteoarthritis. Prolotherapy is commonly used for these musculoskeletal conditions which are refractory to usual care therapies. The proliferant solution and technique varies according to physicial training and preferance. Commonly reported proliferants include 10% to 25% dextrose, P2G and sodium morrhuate. High resolution ultrasound imaging of musculoskeletal tissue is increasing in popularity because of patient tolerability, low cost, ability to visualize tissue in real time motion and superior resolution of highly organized tissue such as a tendon. This procedure can be introduced by ultrasound imaging and tissue growth and repair after this procedure in a tendon or a ligament can be documented with ultrasound.
